Churn-motor



UNITED STATES PATENT ()FFICE.

GEORGE C. QUICK, OF CENTRALIA, ILLINOIS, ASSIGNOR OF ONE-HALF TO THOMAS QUICK, OF ST. LOUIS, MISSOURI.

CHURN- MOTOR.

SPECIFICATION forming part of Letters Patent No. 253,424, dated February 7, 1882,

- Application filed December 12, 1881. (No model.)

To all whom it may concern:

Be it known that I, GEORGE C. QUIoK, of Centralia, in the county of Marion and State of Illinois, have invented a certain new and useful Improvement in Churn-Motors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class of churnmotors which operate the churn by means of a gravitating'weight; and my invention consists in the construction of the frame or derrick which supports the operatingweight, and

also in the general construction of the operatism, and showing the supporting-frame in section on line 2 2, Fig. 1; and Fig. 3 is a rear View with the churn removed.

A is the churn, which rests upon a projecting end, I), of the bottom of the box B, whose sides give journal-bearing to the shafts of the operating mechanism.

C is a standard or'post stepped into the bottom of the box B. This post is made in two pieces, hinged together at 0, so that the upper portion may be turned down, as shown by dotted lines, Fig. 1, for convenience in shipping the device. The upper portion is held in its working position by a key, 0, passing through staples in the two members. On the top of the post C is a right-angle piece, C, which supports a pulley, C over which the operatingrope D passes.

C is a brace.

E is the operating-weight secured to one end of the rope D, the other end of the rope D being secured to the drum F, whose shaft f has 0 journal-bearing in the sides of the box B. On

one end of the shaftf, outside the box, is acrank,f, for turning the drum to wind the rope thereon. On the other end of the shaft f,within the box, is a loose cog-wheel, f which engages with a pinion,f on one end of a shaft, f which also has journal-bearing in the sides of the box B. On the other end of the shattf is a cog-wheel, f ,-which engages with a pinion, f on one end of a shaft, f which likewise has journal-bearin g in the sides of the box. On the other end of the shaft f outside the box, is a crank-arm, f g

f 9 is a short arm or link connecting the crank f 8 with the vertical connecting-rod f whose upper end is adj ustably connected to one end of a horizontal arm, f whose other end'is adjustably connected to the dasher a, of the churn A. The arm f 9 is adjustably connected to the crank f as shown in Fig. 8. The connections are made adjustable for the purpose of increasing or diminishing the stroke of the churndasher. The arm f is fulcrumed at or near its center to a post, f supported by a frame, f. The rodf works in elongated holes in the outer ends of guide-arms f, which arosecured by their other ends to the frame f.

The operation is as follows: The dasher of the churn being connected to the driving mechanism at the proper adjustment, according to the amount of cream in the churn, the rope D is next wound upon the drum F by turning the crank f until the weight reaches the top of the supporting-post. Itigidly secured to the end of the drum, or to its shaft, is a ratchet-wheel, h, which is engaged by a pawl, h, on the cogwheelf When the drum is turned to wind up the rope the pawl slips over the teeth of the ratchet-wheel, allowing the wheelf to remain still, and when the rope is unwound from the drum the pawl engages with the ratchet-wheel, which turns the wheel f and through the system of gearing, operates the churn-dasher.

When the rope is all wound upon the drum the crank is released and the weight gravitates and operates the parts.

The motive power may be increased or diminished by achan ge of dilieren t-sized weights. A small amount of cream would, as a matter of course, require less motive power than a large amount of cream.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

The combination of churn A a, connectingarm f, fulcrumed on post f, frame f, connecting-rod f guide-arms f arm f crank f box B b, gearingf f f f*f f f, drum F, crank f, ratchet-wheel h, pawl h, rope D, Weight E, pulley C and supporting-post C C, all made substantially as and for the purpose set forth.

GEORGE C. QUICK.
